ROAD-BED AND LEVELEB.

Specification of Letters Patent.

Patented Apr. 27, 1915.

Application led February 7, 1914, Serial No. 817,092. Renewed Karch 25, 1915. Serial No. 17,049.

To all whom it may concern Be it known that I, FREDERICK U. ADAMS, a citizen of the United States, residing in Hastings-upon-Hudson, -in the county of Westchester and State of New York, have invented certain new and useful Improve.-l ments in Road-Beds and Levelers, of which the following is a specification.

My invention constitutes an improved reinforced concrete railroad bed characterized by a longitudinal system of construction, uniform and reliable support for the rails and their easy lining-up, repair and replacement, ample bearing on the earth, and safety from heaving and excessive strains.

In the drawings, Figure 1 `is a smallscale plan of two bays of single track substructure and Fig. 2 a transverse section thereof. Fig. 3 is a large scale plan of part of a bay, Fi 4 a corresponding transverse section and ig. 5 a fragmentary side view. Fig. 6 is a small-scale plan of two bays of double track sub-structure and Fig. 7 a corresponding section. Figs. 8 and 9 illustrate a variant in which the rails and ties are borne by leveling devices; Fig. 8 being an side view, partly in section on the line 8--8 of Fig. 9 and Fig. 9 a section on the staggered planes indicated by the lines 9-9 and 9-9, of Fig. 8.

In general terms m invention constitutes a permanent su structure of reinforced concrete, extended below frost, and

comprising longitudinal or sleeper walls conl tinuously supporting the rails and tied at suitable intervals by transverse walls which extend outwardly in buttresses and increase the transverse stability; anchor bolts set in the concrete for the rail system; and gravel or other ballast fllin the cells; and a rail system comprising s eeper, gage and tie plates and rail clamps, all suitably united, golted except where bolts are unfit for the uty.

In the drawings 1, 1, are longitudinal or sleeper walls directly supporting the rails and tied at suitable intervals by cross-walls 2, in line with which are buttresses, 21, which s read the base and increase the latel al sta ility. The walls are illustrated as having the conventional batter; but they might have plumb faces. AnchorV bolts 1 are bedded in the walls in proper locations and sets, for the rails; as are steel reinforcements r. The cells are filled with tamped ballast B.

In the variant illustrated in Figs. 1 to 7 inclusive, the rail base comprises sleeper plates 3 suitably bedded on the walls 1; and

gage-and-tie plates 4, alined thereon by suitab e liners 4 interposed between their downbent ends 41 and the walls, and contain slots 42 for the bolts 1b which bind said ends. T-rails 5 are clamped to the tie plates 4 and substructure by clamps 6, slotted for and secured by the anchor bolts 1a and their nuts and whose clamping ends may extend across the rail tread to and constitute buttresses, 61, bearing against and supporting the web o the rail.

The double track road bed, Figs. 6 and 7, is like the single track save that the cross walls 2 unite the tracks; and the large cells between the tracks are not ballasted.

In the variant illustrated in Figs. 8 and 9, I interpose between the substructure and the rail system, levelers 7 adapted to be manipulated tol quickly rectif defects in the tread-height of the rails. aid levelers are preferably screw jacks of a suitable type. illustrate vertically acting jacks comprising nuts 70, formed with sockets 71 for sleeper plates 3; coacting therewith and abutting on ase plates 19, set in the wall, and centered thereon by the engagement of a stem and sockets, screws 72 provided with jam-nuts 74 and suitable heads 7 3, to which spanners or wrenches can be applied/to operate the jacks.

For conyenience, recesses 18 are formed in the sleeper walls for the jacks.

In the variant the rail system is substantially such as hereinbefore described save that the down-turned ends 41 of the ties 4 are each lateral] secured by two bolts 1b to plates 40 whic extend across the recesses 18; and the rail system is held clear of the substructure by the levelers 7.

I claim:

1. A road bed comprising a reinforced concrete substructure and borne thereby a metal superstructure; said substructure comprising sleeper walls and rail-bolts fixed therein, and cross walls and buttresses in line therewith; and said superstructure coniprising sleeper plates, cross ties formed with down-turned ends and bolt-slots, T-rails, rail-clamps formed with rail-web-buttressing IBO extensions and bolt-slots and serving to adjustably bolt said rails to said tie plates and substructure by means of nuts engaging said rail-bolts; cheek plates between the down-turned tie ends and the sleeper walls, and cheek bolts bolting and laterally confining the last named parts.

2. In combination, a road-bed comprising a reinforced concrete substructure and a superstructure; said substructure comprising sleeper walls and rail-bolts fixed therein; said superstructure comprising sleeperplates, cross-ties, T-rails, and rail clamps; and adjustable levelers interposed between said substructure and said ties and rails, and 15 means to secure the ties and rails to the levelers and to the substructure.

3. A road bed comprising a reinforced concrete substructure; a metal superstructure comprising metal cross ties and T-rails; and screw -jacks interposed between said substructure and said ties and rails; and means to secure the ties and rails to the jacks and to the substructure.
